DNA may grab most of the attention, but another nucleic acid is also available - RNA. Find out how much you know about this major macromolecule in our fun and insightful RNA quiz.

Proteins are one of the major building blocks of life, without which there would be no life as we know it. Want to brush up on your knowledge of proteins? These articles will give you an insight into how and where proteins are made, what they do, and how they are used in science and industry.

Since Crick and Watson’s discovery the world has gone DNA crazy. Have you kept up with developments, with the science of the times? Or do you know more about your jeans than your genes?

Just ten years removed from the sequencing of the entire human genome, we have entered a golden era of genetics. Indeed, genetic discoveries are being made at a furious pace in laboratories throughout the world. Read on to learn about common, important genetic research tools and how they are used.

Scientists today are conducting genetic studies using microarray technique. The main advantage of this technology is that scientists can study thousands of genes at a time. Learn more about this technology, its application and limitations.

There have been several studies that clearly demonstrate the role of genetics and the limbic system in aggression. Although the subject of aggression can be quite complex in human beings, this information will hopefully shed light on the limbic system genetics aggression relationship.

Most eukaryotic cells possess organelles known as mitochondria. These mitochondria are quite special, due to the nature of the DNA they contain. This article discusses human mitochondrial genetics and its possible uses.

Have you been more influenced by nature (genes) or nurture (environmental factors) in your development? Both components play a vital part in all of our lives.

One of the processes steering allelic frequencies, is genetic drift. This random process influences genetic variation. This article discusses three ways it does this.

What is genetic variability and how is it different from genetic variation? This article provides a definition of genetic variability, explains the difference with variation and details the significance of the concept.
